MBM File Format

The MBM image format is associated with a currently obsolete Personal Digital Assistant (PDA), called Psion Series 5. The device was released in 2 variants at the end of the 1990s, including what was regarded at the time as innovative technology and design. MBM files were designed to work in EPOC, an operating system later developed in upgraded versions by several large manufacturers of mobile devices, such as Nokia and Ericsson.
